Countries used to routinely go on domination quests for land and resources. They used to go find exotic lands and claim them as their own. They used to harvest resources and enslave the losers.
Now, not so much. If you watched it zoomed out as a game, you'd assume the powerful players all got bored with it and gave up.
Of course, realizing it's not a game but real people, you realize the world collectively is probably in a better place. But it also means powerful countries giving up power, which is weird to see happen.
